To all 'whom it may concern:

Beit known that I, CHARLEs HENRY FRY, J r., a citizen of the United States, residing at Bellaire, in the county of Belmont and State of Ohio, have invented new and useful Improvements in Lanterns, of which the following is a specification. I A

I have improved the lantern of that class in which a chimney is used of a height less 1o than that of the globe. The short chimney is supported bya foraminousband placed around the burner-cone; and as such chimney has no "support at its top I provide means for securing it to the foraminous band, so that the lantern can be swung and sudden-lyT raised and lowered without danger of displacing the short chimney. In connection with such chimney I use a perforated band supporting the globe, a dome without interior cap, and an air downzo take around the foraininous band at the base of the chimney, the said perforated globeband serving to supply air to the burner-tube through the downtake, to the combustion chamber or chimney through the foraminous band,

that in swinging the lantern the flame cannot i be eXtinguished,\vhile under a sudden descent of the lantern the upward rush of air in the globe-chamber is met by descending currents unaffected by such movements. Under a sudden ascentof the lantern the air-currents e11- tering the dome will be diffused in the globechamber, and there will be no return drafts 3 5 and currents through chimney and globe. 'lhe `draft gives a steady and bright iamc, and it cannot be extinguished in any use of the 1antern.

Referring to the accompanying drawings,

4o Figure l represents a vertical section of alantern embracing my improvements; Fig. 2, enlarged detail views, showing the means of securing the short chimney upon its foraminous supporting-band 5 and Fig. 3, a top view of the the chimney-band, and a bottom view of the chimney, showing the notched rim.

In a patent granted to me November 23,

1880, I used a long chimney with top fastenings anda ventilator-cap within the dome; 5o and my present improvements are designed more especially to produce a cheaper lantern with a short chimney serving only to give steadiness to the Iiame. The cup parts are constructed the same as in my said patent, so as to form an air downtake or passage, c, surrounding the base of the burner-cone b, and communicating with an annular space, c, for the supply of air beneath the burner. In forming this air-downtake the cup-ring d, the 6o perforated globe-band ring e, and the skirt f surrounding the burner-tube and depending from the burner-cone co-operate to supply the flame-tube under the cone with fresh air,` while the foraminous band g, which supports the short chimney h, supplies fresh air to the flame a-nd draft to the chimney. The foraininous bandg is arranged in a horizontal plane with the perforated globe-band z',- and, while supporting the short chimney in place over the 7o burner-cone, it also serves to prevent sudden puffs of wind striking the dame through the openings in the globe-band.

Ihe chimney maybe placed on the inside "or on the outside of the band g; but,in whichever way, it is secured therewith so thatit cannot become displaced in swinging or handling the lantern. A close fitting with the band is not sufcient for this purpose, and besides, such close fitting' is liable to break the chim- 8o ney. A simple form of such fastening is made by a corrugation, s, around the band g, `so as to form a seat for the chimney, and projecting lips r, at the top edge of the band, with corresponding notches u in a rim-projection, lu, at the lower edge of the chimney, to form locks to hold it securely. y

In placing the chimney upon the band the lips r and notches u are brought coincident, the chimney pressed down upon-the corruga- 9o tions s, and then turned to make the lock. rIhe foraminous band is secured to the globeband by arms w, secured to the globe-band ring.

The dome a' has no interior obstruction, and, 95 by its perforations z, affords free circulation of air between it and the top of the short chimney, preventing the undue heating of the dome and any direct downward'draft in the chimney.

I use a perforated band for the globe because it answers the same purpose as an annular opening and makes a safer support for the globe than clamping it upon the ends of wire supports. The perforated band is also better in excluding rain than an open space above the top edge of the globe-band; and I iind that the perforated globe-band and the foraminous chimney-band give the required draft, both to the globe and to the chimney, in eX- peiling the hot air from both through the dome-openings. The non-perforated part of the globe-band is tted and secured within the cup-band in the usual manner, and the lantern is otherwise provided with the proper appliances.
